During a geosteering operation the well path is intentionally adjusted in response to the new data acquired while drilling. To achieve consistent high-quality decisions, especially when drilling in complex environments, decision support systems can help cope with high volumes of data and interpretation complexities. They can assimilate the real-tim...

... complex earth models can not typically be represented using a Gaussian distribution, and consequently EnKF updates will not retain the geological complexity [28]. In this paper, we introduce important elements to make the DSS better suited to real operations, see Figure 1. The main novelty in our approach is to introduce a machine-learning method to represent both the earth model and the forward model of extra-deep borehole electromagnetic (EM) measurements. ...

This paper examines the efficiency of a recently developed Nesting with Data Assimilation (NDA) method at mitigating errors in heat and momentum fluxes at the ocean surface coming from external forcing. The analysis uses a set of 19 numerical simulations, all using the same ocean model and exactly the same NDA process. One simulation (the reference...
